AUGUSTUS G. BURTON, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO CHARLES R. HADLEY AND IVILLIAM A. VAVV- LER, BOTH OF SAME PLACE.

TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 472,665 dated April 12, 1892. Application filed July 24, l89l. Serial No. 400,552- (No model.)

.To all whom it may concern.-

Be it known that I, AUGUSTUS G. BURTON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in temporary binders of that class wherein the sheets or leaves to be bound or held in place are secured between two main lids by being placed over rods or wires that are passed from one lid to the other and which are usually permanently secured to the bottom or back lid and over which the front or upper lid is placed by means of suit-able holes or apertures in said upper lid.

The invention consists in the novel devices and combination of devices illustrated, described, and claimed, whereby the upper lid may be locked in position upon the said rods or wires so secured to thebottom or lower lid.

In the drawings, Figure 1 is a perspective View of a temporary binder embodying my invention. Fig.2 is a plan view of the top bar, to which the locking devices are secured, the said devices being shown in their unlocked position. Fig. 3 is a similar view showing the lockin g devices in their locked position. Fig. 4 is a transverse vertical sectional view taken upon line 4 4 of Fig. 2. Fig. 5 is a rear elevation, partially in section, of the entire device adapted to be secured to the top and bottom lids of a temporary binder.

Let A represent the lower lid, A the upper lid, and A the several sheets of paper secured between said lids.

B is the lower bar, and B the upper bar.

I and plated or otherwise ornamented and protected.

B are rods secured permanently at one end to the bar B at a suitable distance apart, as shown clearly in Figs. 1 and 5. These rods B extend through openings 1') in the bar B, the openings 1) being sufficientlylarge to permitthe bar B to be moved freely upon said rods B The bar B is usually-secured to the upper lid A, so that all or a portion of its surface will be concealed from view, although, as shown in Fig. 1, it may be separate therefrom and exposed to view. It will be understood, of course, that the upper lid A is provided with holes or apertures similar to the openings b in the bar B and which register with said openings I), through which the rods B pass. The upper lid A and the upper bar B are secured in any desired position upon the rods B by reason of the pressure or contact levers C C, which are actuated by suitable means to move in opposite directions and against said rods B As shown in the drawings, each of the levers C C is pivoted at c to the bar B, and they are each provided with a laterally-extending arm or toe c. The lever C is somewhat longer than the lever C and is provided at its inner endwith two arms 0 having their interior and adjacent margins parallel, whereby an opening or slot 0 is provided. The inner end 0 of the lever C is adapted to enter the slot 0 between the ends of the arms 0 0f the lever C, and therefore is actuated whenever the lever C is actuated.

D is an eccentric pivoted at d to the bar B in such position with respect to the pivotal points 0 that the arms 0 will pass on either side of said eccentric, and thus be operated by the rotation of said eccentric, as will be clearly understood by reference to Figs. 2, 3, and 4 of the drawings.

d is a suitable pin or handle by which the eccentric may be operated, a somewhat different-shaped handle or thumb-piece being indicated by the dotted lines in Figs. 4 and 5 at d and which may be employed, if desired. Any other suitable device for turning the eccentric D may be employed-as,forinstance, a squared head 61 to receive a suitable key, as shown in Fig. 2. The 1 outward and lower margin 0 of each of the arms 0' is so shaped that when the levers C C are positioned as shown in Fig. 2, (that is, so as to permit of the bar 3' being moved freely with respect to the rods B said margins 0 will clear the marginal edges of the openings 1), and thus clear the rod 13 It will thus be obvious that when the levers are in the position shown in Fig. 2 the top lid A and bar B may be lifted upwardly and entirely away from the rods B hen it is desired to secure the upper lid A and the bar B to the rods E the handle cl is grasped and turned, thus rotating the eccentric D upon its pivot (Z and actuating the levers C G into the position shown in Fig. 3, with the margins c of the arms 0 of said levers firmly impinging against the inner or adj aeent sides of the rods B and thus looking the several parts together.

The arms 0 of the levers C C may be made to engage the rods B from the outside, it desired,by a slight change in the relative size and position of the parts.

Mydevice is very simple, cheap of construction, will not easily become deranged or get out of order, and thus the costof repairs is reduced to a minimum, and at the same time it is easy of operation and effective for its purpose.

I claim as my invention- 1. In a temporary binder, the combination of the lower bar 15, provided with rods B'-,secured thereto the upper movable bar 1 provided with suitable apertures through which the rods B pass, and means for locking the movable bar to said rods, comprising two levers pivotally secured at their outer ends to said movable bar and adapted to engage the said rods, and an eccentric adapted to actuate the inner ends of said levers and press their other ends against said rods, substantially as described.

2. In a temporary binder, the combination of the bar B, provided with rods E the bar 13, provided with suitable apertures therethrough, the levers CC, pivoted at their outer ends to the bar B and provided with engaging arms 0', and the eccentric D, pivoted to the bar 13, the inner end of the lever C resting against and being actuated by the said eccentric D and engaging the inner end of the lever C to actuate the same, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
